Journal of Advances in Modeling Earth Systems, 2022 This study examines how the congestus mode of tropical convection is expressed in numerical simulations of radiative‐convective equilibrium (RCE). We draw insights from the ensemble of cloud‐resolving models participating in the RCE Model Intercomparison

A stable static Universe? [PDF]
, 2004 Starting from the assumption that general relativity might be an emergent phenomenon showing up at low-energies from an underlying microscopic structure, we re-analyze the stability of a static closed Universe filled with radiation.

Dynamical Instability of Self-Tuning Solution with Antisymmetric Tensor Field [PDF]
, 2001 We consider the dynamical stability of a static brane model that incorporates a three-index antisymmetric tensor field and has recently been proposed as a possible solution to the cosmological constant problem.

TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2002 To systematically study the static stability for airplanes, we proposed the system of definitions of six static stability concepts. The details of “static flight speed stability” and “static angle of attack stability” were discussed in the first report of this paper, and “static pitch stability” was studied in the second.

System static voltage stability analysis considering load characteristics of electrolytic aluminum
Energy Reports, 2022 The load characteristics have a significant impact on the static voltage stability analysis of the power grid. Wenshan power grid has a large amount of relatively centralized electrolytic aluminum load, accounting for 65% of the total local load.

Charged Thin-shell Gravastars in Noncommutative Geometry [PDF]
, 2017 In this paper we construct a charged thin-shell gravastar model within the context of noncommutative geometry. To do so, we choose the interior of the nonsingular de Sitter spacetime with an exterior charged noncommutative solution by cut-and-paste ...
